A surgical instrument adapted for applying a plurality of surgical fasteners to body tissue is provided, comprising a flame having a proximal handle and a distal end effector that is shaped and dimensioned for supporting a cartridge housing and an anvil which are movable relative to one another The surgical instrument further comprises a firing mechanism associated with the end effector and the cartridge housing for selective actuation of the fastening elements for treatment of an individual and a tissue retention feature associated with the cartridge housing and anvil, the tissue retention feature maintaining tissue within the end effector during treatment. The cartridge housing includes staple lines defining the longitudinal extend of the staples being applied via the cartridge module, and the longitudinal extent of the staple line is greater than the longitudinal extend of the tissue retention feature.
